Fc 51 Ir Sensor Datasheet Official
The FC-51 IR Sensor: Your Robot’s Secret "Spidey Sense" Ever wondered how those clever little vacuum robots avoid tumbling down the stairs or crashing into your favorite vase? Most of the time, they’re using a "Spidey sense" powered by infrared light. At the heart of many beginner DIY projects is the FC-51 IR Obstacle Avoidance Sensor
| Feature | FC-51 | TCRT5000 (on FC-51RA module) | | :--- | :--- | :--- | | | Obstacle avoidance / proximity detection | Line following / color detection | | Detection Range | 2 – 30 cm (adjustable) | 1 – 6 mm (very short) | | Output Type | Digital (via LM393) | Digital and Analog (often both) | | Core Sensor | Discrete IR LED + Phototransistor | Integrated TCRT5000 reflective sensor |
The FC-51 module utilizes an infrared transmitter (IR LED) and an infrared receiver (Photodiode) mounted side-by-side. Fc 51 Ir Sensor Datasheet
Place your target obstacle at the desired maximum detection distance.
If an obstacle appears in front of the sensor, the IR light reflects off the object and is directed back towards the sensor. Detection: The photodiode detects this reflected IR light. The FC-51 IR Sensor: Your Robot’s Secret "Spidey
The FC-51 module is compact and features a small number of components. Understanding the layout is crucial for correct wiring.
Used to adjust the detection range sensitivity. Turning it clockwise increases the detection distance. Place your target obstacle at the desired maximum
int sensorPin = 8; // Digital pin connected to the sensor's OUT pin int ledPin = 13; // Built-in LED on the Arduino board
As noted in third-party research, a single "official" FC-51 datasheet from a specific manufacturer has not been universally identified. However, consistent technical details are available from multiple online electronics retailers and tech forums. For definitive information, always consult your particular module's accompanying documentation or the datasheets of its key components: the and the IR emitter/receiver pair .
Includes an onboard "blue trim pot" used to adjust the sensor's sensitivity/range. Pin Configuration
